An ATV piston is a component of reciprocating engines, pumps and gas compressors. It is located in a cylinder and is made gas-tight by piston rings.

High-quality ATV Pistons.
In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder wall. A piston is located in a cylinder and is made gas-tight by piston rings.

Piston Manufacturing Techniques.
Pistons are manufactured via a cast or forged technique. Some consider hypereutectic pistons to be the "third manufacturing technique", but as they are actually a cast piston with physical properties that fall between cast and forged pistons due to their unique aluminum alloy. Cast pistons are made by pouring melted aluminum into a mold that shapes the metal into a piston.

Forged pistons are formed using a giant press that takes a block of metal and pounds it into shape under thousands of tons of pressure. The tooling needed to do this is much more expensive than the tooling used to make a casting, and it wears out quicker. This makes forged pistons more costly. Forged pistons have inherent advantages in terms of density, ultimate strength, and durability. Forging eliminates metal porosity, improves ductility, and generally allows the piston to run cooler than a cast unit. Within reason, forgings can be lightened without adversely affecting structural integrity. Forged pistons however, expand and contract more under changing temperatures, so they traditionally require greater piston-to-wall clearance than cast pistons. The manufacturing technique produces a metal slug, which is then CNC milled to produce the final piston shape.
